After latest update (with installing steam-arch-transition) I’m unable to start Steam on Fedora KDE, because ubuntu12_32/steam keeps coredumping.
Anybody figured out what can be missing or if it is a general problem?
Terminal output:
steam.sh[42429]: Running Steam on fedora 44 64-bit
steam.sh[42429]: STEAM_RUNTIME is enabled automatically
setup.sh[42483]: Steam runtime environment up-to-date!

Looks like steam didn't shutdown cleanly, scheduling immediate update check
